On device.This is also along with appearance the problem of how effectively monitoring this kind of interface in production process, and wherein the screen of TFT material is surveyed
It is larger to try difficulty, and test index has typicalness.
At present the test item of TFT screen include: brightness, resolution ratio, contrast, pixel, pixel away from etc..Wherein pixel
The test of point has high requirement to the sampling of image.Traditional test mode is being shielded by a high-precision camera
The surface of curtain is taken pictures sampling, and the problems such as due to focal length and light shooting angle, reliable sample range is extremely limited.
Summary of the invention
The purpose of this utility model is to provide a kind of TFT test device, the side shot simultaneously using three industrial cameras
Case passes through three groups of data when eliminating the influence of light angle when shooting, while measuring same pixel in same area
Calculating reduce influence of the systematic error to test.Solve problems of the prior art.
To achieve the goals above, the technical solution of the utility model are as follows: a kind of TFT test device, described device include
Device frame, the lower part of device frame are power control cabinet, and the top of device frame forms display equipment cabinet, formed in the middle part of device frame
Test cabinet, the bottom surface of test cabinet are equipped with station, and a sleeve clamp is equipped at station, and station surface forms the test of TFT screen
Station, the above-mentioned fixture corresponding matching TFT screen test station form partition institute between test cabinet and the display equipment cabinet on top
It states and is lifted with 3 industrial cameras at partition, wherein an industrial camera is located at centre, is located in the middle this industrial camera and hangs down
It is directly projeced into the TFT screen test station of lower part, in addition two industrial cameras are set to the two sides of that intermediate industrial camera, and two
The oblique TFT screen test station for being projeced into lower part of two industrial cameras of side, three industrial cameras are arranged in same level
On, and triangular shape is distributed in same level, and three industrial cameras are located at an apex angle position of triangle
Place, every industrial camera configure a LED light supplement lamp.
The utility model discloses a kind of TFT test device, compared to the test TFT screen that tradition uses single camera,
The processing for increasing sampling picture using three camera schemes reason in testing process, increase to TFT screen parameter test can
By property；Improve the testing efficiency of TFT screen test；The range for increasing camera sampling, to the type of same testing station test product
Extension, reduce and build the cost of test device again, to guarantee accuracy that subsequent parameter compares.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
